I just upgraded to Windows 10. I have SplitCam 7.4.4.1. Before the upgrade it worked fine. Now it doesn't seem to be transmitting anything. I tried two sites. Both work with the native Logitech Webcam Software. I unloaded this software and restarted SplitCam and it shows me in the window, so it was connected properly to my webcam (Logitech Pro 9000), but nothing gets transmitted to the web site. I haven't changed any configuration settings since it worked under Windows 7. Any ideas?

Splitcam has a driver for each OS. So if your OS was Win7, then splitcam set the driver for win7.
You have upgraded OS to Win10, then you should reinstall the program for set of the corrected driver for this OS.

I did uninstall/reinstall but still had problems, however I played around a bit with some Windows 10 privacy settings and the software does now seem to work, but not on every site. That indicates to me that the issue is not with SplitCam but with sites that haven't updated their software to work with Windows 10. In any, thanks, and you can close out this problem report.

For future reference, if others have similar issues, have them check two things: windows 10 camera privacy settings and the firewall settings in their antivirus software. I use BitDefender and it has specific controls giving permission to SplitCam.

You are right - at first splitcam start the antivirus can block the output to Inet. Usually it asks you to permit the program to go across its firewall. You confirm this permit and the problem goes away.
We also had the issue with 360 Total. This antivirus removed splitcam.exe after installation. Usually all our exe/dll/sys files have a dual signing of CA and any antivirus must skip them, but not for 360 Total. The problem was resolved by my email to their support.

Thanks again. I use Firefox V 47.0.1. I tried both of the sites you suggest for testing and both work fine. As I said, I view this issue as closed.

I did notice one thing. When connecting, to the HTML5 site I am offered the choice of 4 video sources: Logitech Webcam Pro 9000, IP SplitCamera, SplitCam Video Driver, and SplitCam Video Filter. Of these, only the last two work and they appear superficially indistinguishable. On the sites I have tried that fail, I am given no choice, so maybe they are arbitrarily picking the wrong one, or possibly their HTML5 is not up-to-date.

I don't know which of SplitCam Video Driver or SplitCam Video Filter I should choose when offered the option. I have been picking the driver.

This is a driver of your webcam. If splitcam is running, then you cannot select that driver because that driver has been captured by splitcam or another app. If you wish to test only your webcam, then close those apps.

2. IP Split Camera

This is a driver for IP cameras. Splitcam set it for capture of their video. If you have not selected any IP camera in splitcam, then you will see a black screen on the test site.

3. SplitCam Video Driver and SplitCam Video Filter

These are the main drivers of splitcam. You should select them for capture of your video in chats/apps. The drivers work the same. Therefore you can select any of them. Why we give two drivers - because the SplitCam Video Driver works in the kernel mode and the SplitCam Video Filter is in the user mode. Some apps can have some problems in one of those modes, then the user will see only one of those drivers.
For example, MS Edge in Win10 x64, you will see only SplitCam Video Driver there.

I have a problem with the latest version of Splitcam since the Win10 anniversary update.

SC works OK but after about 5-10 minutes it causes the windows camera service to use 30+% of CPU cycles. Shutting down SC lets that service return to normal. It makes SC unusable unfortunately as the cam slowly grinds to a halt. My camera is Logitech HD Pro C920, drivers are up date date.

I reset the video configuration as you suggested, started SC which functions OK, but this service I mentioned just slowly increases CPU use until the cam freezes. After 10 mins the service is now taking up 20% of my CPU and still going up, SC its usual 10% or so.

Notwithstanding my previous comments, there appears to be an issue with the latest Logitech software and drivers with the latest version of win10. I have installed the windows standard driver for the cam instead of the Logitech ones and all seems OK. So apologies, its not a sc issue it appears.
